The Lick AGN Monitoring Project 2016: Velocity-Resolved Hβ Lags in Luminous Seyfert Galaxies
Vivian U, Aaron J. Barth, H. Alexander Vogler +61
We carried out spectroscopic monitoring of 21 low-redshift Seyfert 1 galaxies using the Kast double spectrograph on the 3-m Shane telescope at Lick Observatory from April 2016 to M…
Gravitational waves from defect-driven phase transitions: domain walls
Simone Blasi, Ryusuke Jinno, Thomas Konstandin +2
We discuss the gravitational wave spectrum produced by first-order phase transitions seeded by domain wall networks. This setup is important for many two-step phase transitions as…
Higgsless simulations of cosmological phase transitions and gravitational waves
Ryusuke Jinno, Thomas Konstandin, Henrique Rubira +1
First-order cosmological phase transitions in the early Universe source sound waves and, subsequently, a background of stochastic gravitational waves. Currently, predictions of the…
Adiabatically compressed wave dark matter halo and intermediate-mass ratio inspirals
Hyungjin Kim, Alessandro Lenoci, Isak Stomberg +1
The adiabatic growth of a central massive black hole could compress the surrounding dark matter halo, leading to a steeper profile of the dark matter halo. This phenomenon is calle…
The Lick AGN Monitoring Project 2016: Dynamical Modeling of Velocity-Resolved H\b{eta} Lags in Luminous Seyfert Galaxies
Lizvette Villafaña, Peter R. Williams, Tommaso Treu +62
We have modeled the velocity-resolved reverberation response of the H\b{eta} broad emission line in nine Seyfert 1 galaxies from the Lick Active Galactic Nucleus (AGN) Monitioring…
A local baseline of the black hole mass scaling relations for active galaxies. IV. Correlations between and host galaxy , stellar mass, and luminosity
Vardha N. Bennert, Tommaso Treu, Xuheng Ding +6
The tight correlations between the mass of supermassive black holes () and their host-galaxy properties have been of great interest to the astrophysical community, but…
Cosmic string gravitational wave backgrounds at LISA: II. Reconstruction of conventional signals over astrophysical foregrounds
Androniki Dimitriou, Daniel G. Figueroa, Peera Simakachorn +2
The paper investigates how well LISA can recover a stochastic gravitational‑wave background from cosmic strings when realistic astrophysical foregrounds are present, using the GWBa…
Gravitational wave spectra for cosmological phase transitions with non-linear decay of the fluid motion
Isak Stomberg, Alberto Roper Pol
We summarize the theoretical framework of gravitational wave (GW) production by bulk fluid motion induced by expanding broken-phase bubbles during a first-order phase transition. U…
Dissecting the Stochastic Gravitational Wave Background with Astrometry
Mesut ÃalıÅkan, Yifan Chen, Liang Dai +3
Astrometry, the precise measurement of star motions, offers an alternative avenue to investigate low-frequency gravitational waves through the spatial deflection of photons, comple…
Gravitational waves from first-order phase transitions: from weak to strong
Chiara Caprini, Ryusuke Jinno, Thomas Konstandin +3
We study the generation of gravitational waves (GWs) during a cosmological first-order phase transition (PT) using the recently introduced Higgsless approach to numerically simulat…
